The ATLAS High Level Trigger's (HLT) primary function of event selection will be accomplished with a Level-2 trigger farm and an event filter (EF) farm, both running software components developed in… (More)

The ATLAS trigger reduces the rate of interesting events to be recorded for off-line analysis in three successive levels from 40 MHz to about 100 kHz, about 2 kHz and about 200 Hz. The High Level… (More)

The pool of persistent objects for LHC (POOL) project, part of the large Hadron collider (LHC) computing grid (LCG), is now entering its third year of active development. POOL provides the baseline… (More)

We present a description (speciication) of a HEP data handling approach based on an Object Oriented Database System and its applications to CDF RUN II. This solution has been proposed and carefully… (More)

The POOL project, as a part of the LHC Computing Grid (LCG), is now entering its third year of active development POOL provides the baseline persistency framework for three LHC experiment and is… (More)

The ATLAS trigger reduces the rate of interesting events to be recorded for off-line analysis in three successive levels from 40 MHz to /spl sim/100 kHz, /spl sim/2 kHz and /spl sim/200 Hz. The high… (More)

Following rigorous software design and analysis methods, an object-based architecture has been developed to derive the second- and third-level trigger decisions for the future ATLAS detector at the… (More)
